Have 3 boys and they all love these! They are super soft and I have machine washed on gentle cycle with Woolite and then 'low heat' dried. I have also hand washed and air dried. Both worked great! I would recommend these for a great base layer the will help keep you warm and dry!! My 7 year old has taken to sleeping in them, and he used to refuse to wear anything to bed. That's how comfortable and temperature regulating they are!
I love this bottom. It is soft and warm. Washing is easy and stays in shape after the washing. Now my whole family has the top and bottom. Must have for winter sports.
I bought these for my 3 sons to wear under their ski pants. It kept them nice & warm through hours of snowboarding in temps in the low 20's F.
Keeps warm and easy to wash - just throw in the washing machine when my son gets it dirty. And it's 100% wool! Love it.
